fix mktemp on macOS

[lugi0]

The creation of a temp dir in the test-output folder for ods-ci appears to be broken in macOS, causing the run_robot_test.sh script to fail when run on a vanilla system using all defaults.
This variation of the command will create a directory called ods-ci-$(date +%Y-%m-%d-%H-%M)-XXXXXXXXXX) within the TEST_ARTIFACT_DIR directory (i.e. by default ods_ci/test-output/).

LGTM

Hopefully this won't break it for some other MacOS users with older systems since I don't understand how it worked for them fine 🙃

Anyway, LGTM now, thank!

I tried it on Mac It does not throw any error, but does not either create a directory called ods-ci-$(date +%Y-%m-%d-%H-%M)-XXXXXXXXXX) within the TEST_ARTIFACT_DIR directory (i.e. by default ods_ci/test-output/)
After triggering Test Case with changes on run_robot_tests.sh:

$ ls -lu /Users/asanzgom/Work/ods-ci/ods_ci/ods_ci/test-output/

@asanzgom Where are you launching the script from? The root of the repo or from its ods_ci subfolder?
From your logs I can see an ods_ci too many in the path
